Soft cheeses can contain listeria bacteria that cause an infection called listeriosis. To avoid this risk, pregnant women are advised to not eat mould-ripened soft cheese.

Soft cheeses can contain listeria bacteria that cause an infection called listeriosis. To avoid this risk, pregnant women are advised not to eat any mould-ripened soft cheese such as brie, camembert, mould-ripened soft cheese made with goats' milk, and others with a similar rind.

You should also avoid eating soft blue-veined cheeses, including:

Danish blue

gorgonzola

roquefort

Soft cheeses like this are less acidic than hard cheeses and they contain more moisture. This means they can be an ideal environment for harmful bacteria, such as listeria, to grow in.

Listeriosis

Listeriosis infection is usually caused by eating food contaminated with listeria bacteria. Pregnant women are more at risk of getting listeriosis because of hormonal changes during pregnancy that weaken the immune system (the body’s natural defence against infection).

Although infection with listeria is rare, it's important to take special care during pregnancy. Even a mild form of the illness in a pregnant woman can cause miscarriage, stillbirth or severe illness in a newborn baby.

Cheeses you can eat

While you're pregnant, it's safe to eat hard cheeses, as well as other types of cheese. Hard cheeses don't contain as much water as soft cheeses, so bacteria are less likely to grow in them.
